Multiple ESC control with arduino

Hi! Excited newcomer to ROVs! We purchased 2 T200s with BasicESC for vertical motion on our ROV. I have seen your example code on how to operate one, but wondering if there is any concern about splitting the signal from the arduino to two ESCs? They will work in tandem with each other.

Not sure why this never got responded to, so I hope you managed to solve this for your original project, but answering now for posterity.

There shouldn’t be any electrical issues with sending the same PWM signal to two ESCs, but note that without individual control it’s not possible to balance the thrusters, so they may have slightly different thrust outputs at a given input signal depending on each thruster’s internal resistance and any minor differences in the magnet, shaft, and coil alignments. I’d expect that effect should be relatively negligible compared to other components like buoyancy and mass distribution, but it’s at least worth a mention.
